Finger twitching

Abnormalities in the musculoskeletal system are often the cause behind any twitching in the fingers, including the index finger. However, there are other reasons why fingers twitch, such as problems with the nervous system. Although much rarer, this symptom can be a result of a combination of issues between both the musculoskeletal system and the nervous system. For a list of the most common and probable causes behind finger twitching, please continue reading.

Even though finger twitching itself, is not a disease, it can be an indication that a disease may be present. That said, finger twitching is often brushed off as a result of insufficient calcium or poor sleeping posture. If these twitches and spasms are ignored, a life-threatening illness could easily pass under the radar. The following is a list of some of the severe illnesses associated with finger twitching.
Possible Causes of Finger Twitching
• Carpal Tunnel Syndrome – Carpal tunnel syndrome happens when the median nerve becomes compressed as it travels through the carpal tunnel. The carpal tunnel is a pathway, located within the wrist, that the flexor muscles and nerves of the hands pass through. This condition can be a result of muscle overuse, vascular malformation, ganglion, or lipomas. Common to severe symptoms of this syndrome are: Pain in the hands, numbness, twitching, muscle cramps, burning sensations, and the inability to grip.
• Parkinson’s Disease – Parkinson’s disease can be one of the more severe causes behind finger twitching and/or spasms. Parkinson’s disease is a life-threatening condition that causes the degeneration of the central nervous system. This, eventually, leads to the deterioration of the person’s motor skills, bodily functions, and speech. Parkinson’s disease is a movement disorder which starts off with muscle rigidity and tremors. Eventually the patient will experience a significant slowing of movement, also known as bradykinesia, and then will go on to experience the complete loss of movement, or akinesia. The reason for Parkinson’s disease is not known but genetics, toxins, cerebral anorexia, and head trauma are all thought to be potential causes. During the initial stages, finger twitching, muscles spasms, and numbness are the most prevalent symptoms.
• Amyotrophic Lateral Sclerosis (ALS) – Amyotrophic Lateral Sclerosis is more commonly known as Lou Gehrig’s disease. ALS is a form of motor neuron disease which is progressive and severe as it causes the motor neurons to degenerate. Motor neurons are the nerve cells within the central nervous system that are responsible for voluntary muscle movement. The onset of ALS is very gradual and is often overlooked. Mild symptoms associated with ALS are cramping, twitching, stiffness in the affected muscles, and muscle weakness within the limbs. These mild symptoms can affect the patient during the initial stages of the disease.
For the most part, finger twitching is not a severe symptom and can easily be cleared up by doing finger or arm exercises as well as making healthy dietary changes. If the condition persists for an extended length of time, you should consult with a doctor immediately. The best way to treat these spasms are by getting an early diagnosis so that treatment can begin as soon as possible.
